For the line perpendicular to y = 12, the slope is undefined because the denominator of the slope is 0. for the line parallel to y = 12, the slope would be 0 because it is a flat line, no slope.

a. x + 2y - 8 = 0
b. 2x + y - 8 = 0
c. 2x - y + 8 = 0

Which expression can be used to determine the slope of the line that passes through the points -6, three and one, -9

Varies inversely with x. if y=8.5 when x=-1 find x when y=-1
